SHOOT: It gets into the stomach, hence the vomiting and diarrhea.
July 2 (Bloomberg) -- Swine flu caused more-severe illness
in ferrets than seasonal flu, according to two studies in the
journal Science that help explain why the H1N1 virus causes
symptoms not seen in regular flu such as nausea and vomiting.
The H1N1 swine flu virus went further into the ferrets’
lungs, and also penetrated the gastrointestinal tract while
seasonal flu stayed in the nasal cavity, researchers from the
U.S. and the Netherlands found. Ferrets are affected by flu
viruses much as humans are, the researchers said.
“These data suggest that the 2009 A(H1N1) influenza virus
has the ability to persist in the human population, potentially
with more severe clinical consequences,” wrote the Dutch study
authors, led by Ron Fouchier at the Erasmus Medical Center in
Rotterdam.
Both groups
found that ferrets infected with swine flu lost more weight than
those exposed to seasonal flu, and that the swine flu virus was
more widespread in the animals’ bodies. |
